Suede-like raised woven fabric and process for the preparation thereof

ABSTRACT

A suede-like raised woven fabric having raised fibers on the surface thereof; consisting mainly of a yarn or thread which consists of a bundle of extra-fine fibers (the monofilament denier of which is 0.0001 - 0.4 d). The preparation of the fabric comprises weaving, using as weft said yarn and using as warp a yarn having a coil-like crimp or a coil-like potential crimp capacity, in the organization of the woven fabric except for the raised portion, which consists of an elastic polymer dispersed and adhered in a fibrous state, and/or as fine pieces of film throughout the said fabric. Said fabric has a high density of suede-like naps, has excellent pilling resistance and, wrinkle resistance, feel, and is suitable for apparel.
